Studies Of Different Covering Materials On Cold-proof Effect Of Blueberry

Blueberry is also called bilberry, it is the cuckoo division (Ericaceae) bilberry genera (Vaccinium SPP.) plants, the fruit in special blueberry anthocyanin substances such as a improve eyesight, anti-aging and cancer prevention, such as effectiveness, is known as "the21st century functional health berries" and "fruit of the empress". And it was listed as one of the five most human healthy food by Agriculture Organization (FAO).The main consumption of blueberry is fresh fruit..And in international market, about60%of blueberry fruit is soled as fresh fruit. The proportion in China is basic consistent The product can far not satisfy the market demand. Blueberry fruit is offered only in the ultra large city and parts of near the blueberry origin city for sale, the domestic part of the provincial capital city level have not form a stable sales, the market space is enormous. At present blueberry fruit origin price and the market price although decreased to different extent, planting benefit is high still. The safeguard of healthy and sustainable development is the base of realizing the blueberry product anniversary supply and meeting the consumption of different people. At present, the blueberry wine, dried fruit, fruit juice and processed products are developed, but it has not formed a large scale for the yield is low,, the main reason is it is affected by the limitation of raw material yield. In the fall of2010, the price of blueberry fruit processing raw material is more than40000Yuan/t, the planting benefit is considerable.Blueberry plants is bush, with branches thin, phloem thinner, hip bigger low.temperature and wind in winter are tend to do harm to the sprout. In Jiao Nan area of Qingdao for the1-2years blueberry, the effect of soil buried measure in the open is good, and it is the most common application at present, but for the3years above plants, the twice plowing of autumn bury and spring dug could cause flying sand up dust, the serious pollution of the environment, at the same time, it can not only do harm to the blueberry branches, but also take a lot of work time consuming, the production does not have operability. In order to solve the blueberry buried soil cold-proof problem existing in the course of environmental pollution and the large work time consuming problem, look for the more convenient, economic and effective exposure method, we have taken the different material thermal effect measurement and cost-effective evaluation research, so as to strive to explore scientific and effective blueberry cold-proof technology, and provide theoretical support for the application of next blueberry industrialization cultivation conditions cold-proof materials in the field.
